Editing Containment Foam (section)

==Traits==
Containment foam is a yellow-white in colour.<ref name=":0">I was stepping behind one of the team members, drawing my knife against the hose that extended between the flamethrower-like device he held in his hands and the tank on his back.  It didn't cut immediately, forcing me to try a second time.  As the knife severed the material of the hose, the PRT team member noticed me and drove his elbow into my face.  My mask took the worst of the hit, but getting hit in the face by a full grown man isn't any fun with any amount of protective headwear.<br><br>I fell back through the doorway even as the tank began emptying its contents onto the floor.  It was a yellow-white, and as it poured onto the ground, it expanded like shaving cream.  The tank was probably close to three gallons, making for a hell of a lot of foam. - [https://parahumans.wordpress.com/2011/12/27 Excerpt] from [[Tangle 6.5]]</ref><ref>Her hands were buried in a pair of reinforced metal buckets, each filled with that damn pastel yellow foam.<br>[...]<br>The girl wore the same orange jumpsuit as Paige, and every part of her except her shoulders and head were covered in the yellow-white foam. - [[Interlude 6]]</ref>

It [[Wikipedia:Spray foam|sprays as a liquid]], then expands into a foam.<ref name=":1"/> The foam is flexible and porous, allowing people to breath while fully entrenched in it, and is extremely sticky. It's impact resistant, so heavy hitters can be contained or safely catch falling individuals. It's also resistant to high and low temperatures<ref>'''Ereus:''' Can containment foam be frozen[?]<br>'''Wildbow:''' Nope [...] Temperature resistant<br>[...]<br>'''Wildbow:''' For both high and low end of the scale[...]<br>'''Wildbow:''' I figured it was was a given, if not already stated in story - [https://forums.spacebattles.com/posts/17284645 Wildbow on IRC], archived on Spacebattles</ref> and insulates against electricity. Its rubbery nature makes it difficult to get leverage once trapped in it.<ref name=":1">The PRT, the Parahuman Response Team, was equipped with tinker-designed nonlethal weaponry to subdue supervillains.  This containment foam was standard issue.  It ejected as a liquid, then expanded into a sticky foam with a few handy properties.  It was flexible and it was porous when fully expanded, for one thing, so you could breathe while contained within it, at least long enough for rescue teams with a dissolving agent to get to you.  It was also impact resistant, so PRT squads could coat the ground with it to save falling individuals or keep heavy hitters from doing much damage.<br><br>The way it expanded, you could coat all but the strongest villains in it, and it would disable them.  Because of the way it denied you leverage and was resistant to impacts and tearing, even the likes of Lung would have trouble pulling themselves free.  Topping it all off, it was resistant to high temperatures and a strong insulator, so it served to handle the pyrokinetics and those with electromagnetic powers. - [https://parahumans.wordpress.com/2011/12/27 Excerpt] from [[Tangle 6.5]]</ref>  Only the strongest villains can escape once caught.<ref name=":2">The other two had what appeared at first glance to be flame throwers; were they to pull the triggers, they would eject a thick, frothing spray of foam, enough to contain all but the strongest and fastest villains. - [https://parahumans.wordpress.com/2011/09/20 Excerpt] from [[Interlude 3]]</ref><ref name=":1" /><ref>The shells exploded into blobs of containment foam, fireproof, sticky, virtually impossible to remove.

But not capable of holding back something like Behemoth. [...] Cryogenic beams, containment foam and more served to slow him down.  Not ''stopping'' him.  No, that was too much to hope for.  His pace was roughly two-thirds the speed it might otherwise be, at a glance [...] More containment foam and more ice built around him, tearing and melting, respectively, in response to his lesser movements. - excerpt from [[Drone 23.5]]</ref>

Even flecks of foam expand into masses the size of golf balls and softballs. Attempting to wipe it off exposes more to the air, making it expand still further.<ref>All in all, Dragon unloaded four streams of containment foam into the lobby, each of the shoulder mounted turrets  gushing like firehoses.  Only flecks of the spray struck us, but they expanded into blobs of foam the size of golf balls and softballs.  Each blob was tacky, sticky, and any attempt to wipe it away just smeared it and exposed more surface area to the air, making it expand more. - [[Parasite 10.5]]</ref> The foam's surface instantly sets into a durable, rubbery solid where it's in contact with solid objects (such as people), holding them in place.<ref>I tried to raise myself to see Dragon looming above, but the foam offered only a rubbery resistance.  It had set with the contact, bonded to my costume.  I was pinned face down on the ground. - excerpt from [[Parasite 10.5]]</ref> Over time, the foam sets entirely; going from soft and incredibly sticky, to tacky but safe to set things down on,<ref>Seeing Bakuda gingerly balance the metal grilles on her free shoulder, against the tacky foam so they wouldn't slip down, Paige did the same with the leather of the mask. - excerpt from [[Interlude 6]]</ref> and eventually ending up hard and crusty (though still somewhat flexible.)<ref>I took the time to shower and don my costume – my sleeve was still crusty and stained yellow-white where it had come in contact with the foam, but at least it wasn't sticky anymore. - excerpt from [[Infestation 11.1]]</ref><ref>I headed upstairs and got my costume on in record time.  I couldn't help but note how dusty it was from last night's encounter, and how the one arm was still crusty with old containment foam.  It was torture to actually get my limbs into the legs and sleeves and zip up, and to contort myself to attach my armor. - excerpt from [[Plague 12.8]]</ref>
